Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.

TCR Screening Services

Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

LSBio Functional ELISA Kits

Functional ELISA kits are a fast and cost-effective way to screen samples for the presence of functional proteins with specific activity characteristics.
Each kit is ready-to-use with all the necessary reagents and a clear, concise protocol that will step you through the process, from sample preparation to analysis of the results.

Functional ELISA Kit Protocol

1) The kit comes with a 96-well microtiter plate that is pre-coated with the target antigen.

2) The sample is added to the well and the target protein binds to the protein substrate.

3) The wells are washed and a primary antibody is added which binds to the target protein.

4) The wells are washed and a HRP-conjugated secondary antibody is added which binds to the primary antibody.

5) The wells are washed and a solution containing TMB is added.
The TMB reacts with the HRP changing from colorless to a blue color.
An acid stop solution is then added, the reaction stops, and the blue color changes to yellow.
The plate can then be read in a spectrophotometer at a wavelength of 450 nm.
